LIMITED SHIPPING CAPACITY MAKES THE EXTENSION OF PRODUCT SHELF LIFE EVEN MORE IMPORTANT (FreshPlaza.com, GCCA News)
Limited shipping capacity is a global problem. Traders in many regions are facing problems with delayed containers. Extending the shelf life and preserving the freshness of crops is particularly important, and reducing fresh produce waste is vital.
Cathy is the sales manager from Chesen BioChem, a 1-MCP producer from China. With the mango peak season coming, Cathy introduced the application of its PlanFresh product on mangos. “PlanFresh™ 1-MCP can maintain the freshness of different crops and can also be applied to the storage and preservation of mangoes. Due to some special physiological phenomena of mangoes, proper pre-treatment is required before using 1-MCP on mangoes.”
“Mango is a climacteric fruit prone to cold damage during low temperatures, while high temperatures will accelerate the rotting process. Mangoes easily deteriorate rapidly in sealed storage. At ambient temperatures, mangoes generally turn yellow as they ripen in 7 to 10 days after picking, and the storage time is very short. And because of the latent infestation of anthracnose in the fruit, even if the ordinary fresh-keeping cold storage can prolong the fresh-keeping storage time, the symptoms of disease will also occur during the post-ripening process. In fact, most of the mango fruits have latent anthracnose. In order to effectively reduce the impact of anthracnose, heat treatment should be carried out after harvesting. The method is to soak the fruits at 47-55 ℃ warm water for dozens of minutes, of course, you can also add fungicide. ”
According to Cathy, mangoes that need fresh-keeping storage mainly are picked on sunny days when there is no dew, and the roundest fruits are chosen. “When the peel of the mango becomes lighter, the flesh turns yellow and some are ripe and fall. That is the suitable picking time. After picking, wash with clean water and remove the mucus flowing from the incision to avoid rotting caused by the sticky mucus of the peel. And the mango fruit must be placed in a cool place in time to dissipate heat. Next you must remove insect-infestations and damaged fruit, sort the mangoes, and then store them in fresh-keeping cold storage.”
Post-harvest management of mangoes is important for traders’ sales activities. “The most critical factor affecting the post-harvest shelf life of mangoes is temperature management. 20 to 25°C is the temperature range that gives the best fruit appearance, palatability and rot control at maturity. And to extend shelf life, you can keep mangoes at 10 to 15°C. In other words, keeping mangoes outside these temperature ranges can result in poor fruit quality, which can harm the fruit.” Cathy introduced.
“1-MCP is an effective inhibitor of ethylene action in fruits, It has been shown to delay the ripening or aging process and to extend the shelf life of many fruits. It acts by irreversibly binding to the ethylene receptor in fruits. Thus, it prevents the effects of ethylene on plant tissues.” Cathy explained, “the successful application of 1-MCP in fruits depends to a large extent on many factors, such as variety, harvest ripening stage, concentration, exposure time and temperature. The treatment time varies from 12 to 48 hours to achieve a complete response. The PlanFresh card is ideally suited for mango preservation, non-toxic, and leaves no traceable residue.”
Chesen BioChem has the license for selling their products in China. “We are committed to the market of pre-harvest and post-harvest agricultural chemicals, and actively promote the overseas registration of agricultural chemicals such as phytohormones. Due to the COVID-19 pandemic, it is a pity that we cannot attend the Fruit Logistica this year, but we sincerely hope to form a strategic partnership with dealers from all over the world, and work together for the prosperity and development of the PlanFresh series and other agrochemicals.” Cathy said (http://www.chesenbio.com)
